Headscratchers / Scooby Doo! Pirates Ahoy!

• So, if the hypnotist needed a specific cartographer to find the meteor, why didn’t he just hypnotize the cartographer?
  • That's why they hit his ship to get him, but he escaped. Rupert wasn't ever alone for the rest of the movie and walked away at the chance Mr. Mysterio otherwise would have got him with the rest of the ship.
• For that matter, how did Mr. Mysterio even find out about the meteor in the first place, let alone that it was made of gold?
